There are two ways to fill basic shapes like lines and rectangles. The first is to use specific drawing methods like Graphics.fillOval(). This example uses these methods. The second is to construct a shape and then use Graphics2D.fill() to fill the s…
一.创建一个包——进行marker练习 1.创建ROS工作空间和包 mkdir -p ~/catkin_ws/src #创建工作空间目录 #创建ROS数据包 catkin_create_pkg using_markers roscpp visualization_msgs #打开包根目录,进行编译 cd ~/catkin_ws catkin_make 2.编写cpp文件,向rviz发送数据 vim ~/catkin_ws/src/using_marker/src/using_markers.cp…

After some thought, I do not believe that pooling operations are responsible for the translation invariant property in CNNs. I believe that invariance (at least to translation) is due to the convolution filters (not specifically the pooling) and due…

究竟该用字体图标.图片图标.还是CSS画一个图标?我也不知道.各有千秋吧.本文将介绍如何用css绘制简单的图形,所有测试在chrome58.0完成,如果你不能得到正确结果请到caniuse查一查看看是不是需要什么前缀. 一.基础 <!DOCTYPE html> <html> <head> <title>basic shapes</title> <style type="text/css"> div{ box-siz…
1.Styled Layer Descriptor 标准描述了稳当的结构合使用规则.一个文档包含了符号定义和绘制规则,那么这个文档就叫做Styled Layer Desciptor(SLD)样式,它是一个text/Xml文件,扩展名为.sld.SLD基于XML标记语言,附加的标准是一个XSD schema,XSD schema定义了SLD语法. 2.样式文档结构 样式最外层部分包含如下片段: <?xml version="1.0" encoding="ISO-8859-…
